Product Description
The evaporating dish is a specialized vessel for evaporation and crystallization
operations in the laboratory. Its design fully considers the operational
requirements of heating and concentration experiments. The flat bottom
provides stable placement on hot plates, water baths, or sand baths,
while the spout facilitates clean pouring of concentrated liquids and
transfer of crystalline products.
Design Features
- Spout Design: A pouring spout on the rim allows clean
transfer of concentrated liquids or crystalline products into receiving
containers, preventing liquid from running down the outer wall and reducing
sample loss and contamination.
- Flat Bottom: Provides stable placement on hot plates,
water baths, or sand baths with large and uniform heating area.
- Shallow Dish Design: Wide opening and shallow depth
facilitate rapid solvent evaporation and convenient collection of
crystalline products.
- Uniform Wall Thickness: Even heat distribution reduces
thermal stress and minimizes the risk of breakage.
Material Advantage
Manufactured from Borosilicate Glass 3.3 in accordance with ISO 3585 standards.
The ultra-low coefficient of thermal expansion (3.3×10⁻⁶/K) ensures resistance
to thermal shock up to 280°C.
How It Works
The evaporating dish removes solvent from a solution by heating, thereby
concentrating the solution or inducing crystallization of the solute.
Widely used in chemical analysis, pharmaceutical production, and research
for sample concentration and purification.
Note: Use a water bath or sand bath for gentle heating during
evaporation to avoid bumping or sample decomposition. Stir continuously
with a glass rod during evaporation to prevent localized overheating.
